Vehicle Parking Lock Manual Release Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The operability of the parking lock manual releasing mechanism in vehicles is impaired due to visibility and accessibility issues related to the installation location, which affects the ability to manually switch the parking lock mechanism from a locked to an unlocked state, especially when the actuator becomes inoperable.
Innovation Solution
A vehicle design that includes a parking lock mechanism with a manual releasing mechanism positioned between the floor panel and the under cover, featuring a visual recognition hole and a working hole in the under cover for enhanced visibility and accessibility of the operation portion, allowing manual operation from outside the vehicle without the need to get underneath it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the parking lock manual releasing mechanism is installed between the floor panel and the under cover, then the mechanism can be protected from external elements, but the visibility and accessibility of the operation portion deteriorates
Solution Approach 1:
The under cover is segmented by providing separate holes: a visual recognition hole for viewing the operation portion and a working hole for manual operation. This segmentation allows the operation portion to remain protected while providing dedicated access paths for visibility and operation.
Solution Approach 2:
The holes in the under cover act as intermediaries, allowing visual and physical access to the operation portion without compromising the protective enclosure. The visual recognition hole provides optical access while the working hole provides mechanical access.
2Ease of operation
If the operation portion is positioned for manual access from outside the vehicle, then accessibility is improved, but the mechanism structure becomes more complex
Solution Approach 1:
The under cover serves multiple functions: it protects the parking lock mechanism while providing visual recognition holes and working holes for operation. This multi-functionality reduces the need for additional protective structures or access mechanisms.
Solution Approach 2:
The visual recognition and working functions are extracted through separate holes in the under cover, allowing the operation portion to be accessed from outside the vehicle while maintaining the integrity and simplicity of the overall mechanism structure.

AI summary
A vehicle includes: a floor panel; an under cover disposed below the floor panel in the vehicle; a parking lock mechanism, disposed between the floor panel and the under cover, switching, using an actuator, a locked state for constraining rotation of a wheel and an unlocked state for not constraining rotation of the wheel; and a parking lock manual releasing mechanism, disposed between the floor panel and the parking lock mechanism, switching, when the parking lock mechanism is in the locked state, the state of the parking lock mechanism to the unlocked state on a basis of manual operation of an operation portion. Further, the under cover includes a visual recognition hole for viewing the operation portion.
